In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: Which group ruled the area for a longer period of time, the Arabs or the Byzantines? Passage:The first permanent Arab settlement on Sicily occurred in 827, but it was not until Taormina fell in 902 that the entire island fell under their sway, though Rometta held out until 965. In that year the Kalbids established the independence of their emirate from the Fatimid Caliphate. In 1061 the first Norman liberators took Messina, and by 1071 Palermo and its citadel (1072) were captured. In 1091 Noto fell to the Normans, and the conquest was complete. Malta fell later that year, though the Arab administration was kept in place, marking the final chapter of this period. The conquests of the Normans established Roman Catholicism firmly in the region, where Eastern Christianity had been prominent during the time of Byzantine rule and even remained significant during Islamic period. Widespread conversion ensued, leading to the disappearance of Islam in Sicily by the 1280s. In 1245, Muslim Sicilians were deported to the settlement of Lucera, by order of Holy Roman Emperor Frederick II. In 1300, Giovanni Pipino da Barletta, count of Altamura, seized Lucera and exiled or sold into slavery its population, bringing an end to the medieval Muslim presence in Italy.

Example Input: Question: Are both football clubs that Hill's team played in the 2002-03 season FA Cup located in England? Passage:He led the club to the Isthmian League title and promotion to the Conference in his first season in charge. The following season, Hill's side finished third in the Conference and took Premiership Charlton Athletic to a replay in the Third Round of the FA Cup. They again reached the FA Cup Third Round in the 2001-02 season, losing 4-1 to Ipswich Town after taking the lead, and finished second in the Conference, missing promotion to the Football League on goal difference. The following season saw another run in the FA Cup, beating Plymouth Argyle after a replay in the Third Round before losing 1-0 to Norwich City thanks to an injury time goal. Their league form was not particularly good until the latter stages of the season when they won eleven consecutive games and qualified for the play-off final, losing 3-2 in extra-time to Doncaster Rovers. The 2003-04 season was not a success and Hill resigned soon after a 9-0 defeat at home to Hereford United late in the season.

Example Input: Question: How old was Charles Laughton when the film he starred in was shown on opening night at the super cinema on Gloucester Place? Passage:The Astoria chain was well established in London by the early 1930s. Cinemas and theatres of that name were built in Brixton (now the Brixton Academy), Finsbury Park, Charing Cross Road, Old Kent Road and Streatham. All were designed by Edward Albert Stone. The brand was soon extended to seaside resorts across southeast England at the initiative of a group of businessmen led by E.E. Lyons. ("Teddy" Lyons had opened one of Brighton's earliest cinemas, the Academy, in 1911 and was well known in the town's entertainment scene.) The group, which also included Sussex Daily News proprietor J.H. Infield (who served as chairman of the Academy Cinema until 1926), had identified a site in 1932 when they planned to open a cinema under the Plaza brand. This did not happen, but in 1933 the consortium commissioned Edward Stone to build a "super cinema" under the Astoria name there. The site was on Gloucester Place, north of Old Steine, and a number of houses from the Georgian and Victorian eras were knocked down to make way. Work began on 17 July 1933 on the 1,823-seat building, which was designed as a combined theatre and cinema with a full stage and dressing rooms. Thursday 21 December 1933 was the opening night; Cooper Rawson and Margaret Hardy, respectively Brighton's Member of Parliament and Mayor, made the inaugural speeches. These were followed by a Movietone News newsreel, features by Pathé and Disney (Santa's Workshop) and the main film—The Private Life of Henry VIII starring Charles Laughton.
